Vertical clips going down the right side.
I never really noticed these until the other day.
The are not riveted or screwed.
They snap into a hole in the seat back.

Johnny - thanks for confirming. I wondered why my car didn't have any clips for the right hand tank there. Now I know. Never seen these clips before and I wonder where I can get them.

Aren't these the little clip thinggies that hold the overflow pipe to the side of the rad?

I believe the part number is 17H9524, in case that helps.

I just checked. They look very similar to the radiator overflow pipe clips but not quite the same. The bit that clips through onto the seat back is shaped differently.

You do, it was & if you don't cross the pipes over watch out!

About 30 years ago I had to stand & watch a MK2 S burn out because I didn't know about this.

Do you have a picture of the part of the clip that fits onto the bulkhead Gordon ?

I have some NOS clips from an old BMC garage and there could be some in with them - probably not but you never know ;)

I don't unfortunately. On my car which had a factory fitted right hand tank there were no clips or tags. I was puzzled about that and so during the restoration of the boot area I welded up all the holes which didn't look right. I suspect I will have welded over the holes which the clips fitted into. The clips in Johnny's photo do look very much like the radiator overflow clip.

That's a right bugger if you have welded up the factory holes Gordon :(

The radiator overflow clip has teeth to grip onto the cowling, in a similar way to the side to side brake pipe clip on the front subframe.

Anyone able to post up a pic of the back of the clip ?

Not the first time I have welded up holes that should be there. You learn as you go along I suppose.

We've all done it, but at least you can re-drill when the faux-pas is discovered :oops:

Me too, less annoying than the two holes I didn't get welded up where the old rubber handle thingy kept the racing fibreglass boot (with no handle) closed! I am putting grommets in mind you as when all said and done, it is part of the car's history.

Here is the back side of the clip, I pushed it out of the hole. This is the lower one. Seems to have dissolved the old vent tubing and bonded together with the remnants. Not a very good venting system.

Thanks Johnny, I'll have a look and see what I've got over next couple of days or so.

Certainly looks sort of familiar ...

Hopefully you do have something like that in your stash of parts. I would certainly be interested if you do.

Anyone know the change over date from the bolted clips to the welded tabs?

Here are some pictures of my Nov 5 built 1275...(complete with factory paint runs).....has the slide in clips.
I suspect that these were eliminated and welded tabs were fitted with the introduction of the RH tank as standard equipment in Jan. 66
P/N 13H9524.....I have a sneaky suspicion that this clip was something that was used on other vehicles. I seem to recall seeing them ...somewhere!
The fact that they appear to be painted green....perhaps they were used on the Lan Rover....just a thought!!!
Pretty sure BMC wouldn't have produced the clip for a small number of RH tank cars.

These small clips and the like wouldn't have been manufactured by BMC but very probably brought in from a small press shops. I know that this is true of a similar round spring clips, also painted green (and blue for the larger size!) used to hold the fuel hoses on MG cars
